I shoot a HEAVY (460+ gr) arrow....on advice from a good friend (thanks, Germ). When you make a great shot.....I'm sure they'll ALL perform well. When you make a marginal shot.....like this one.....



....you'll appreciate the Muzzy. This low shot went through the front side shoulder.....through the vitals and exited through the off side brisket and into the off side front leg. I like the muscle of the Muzzy for THIS reason. I'm not always making perfect shots.
